| (54) | Systems and methods for obtaining and using nonvolatile memory health information |
| (57) Systems and methods are provided for obtaining and using nonvolatile memory ("NVM")
health information. Health information can include a variety of information associated
with the performance and reliability of portions of an NVM device, such as the number
of errors detected in a portion of NVM or the amount of time required to read from
or program a portion of nonvolatile memory. During operation, address specific health
information may be stored passively on a host device and provided as part of a command
to a memory controller. The memory controller may extract the health information from
the command and use the information to execute access requests. After an access request
is completed, the memory controller can update the health information and transmit
the information back to the host device.
